BYQ28EB-150-E3/81, a type of diodes, rectifiers, and arrays, plays an important role in many industrial and commercial applications. It offers high performance, fast switching speeds, and improved reliability. This article will discuss the application field and working principle of the BYQ28EB-150-E3/81.

The BYQ28EB-150-E3/81 is a three-phase bridge rectifier. It is designed with a high temperature symmetrical silicon structure, fast switching speed, low forward voltage and reverse current, low reverse recovery time, and high surge capability. This makes it particularly suitable for high frequency rectification in solar inverters, wind turbines, motor drives, and LED lighting applications.

The BYQ28EB-150-E3/81 has a maximum blocking voltage of 600V and a controllable current capability of up to 150A. It can be used for both AC and DC applications. It is also able to operate over a wide range of temperatures, ranging from -25℃ to 125℃, making it suitable for harsh environments.

The working principle of the BYQ28EB-150-E3/81 relies on PN junction diode technology. The PN junction diode is the most common type of diode, and works by allowing an electric current to flow in only one direction. That is, it allows direct current (DC) to flow in one direction, but does not allow alternating current (AC) to flow in either direction. This means that a PN junction diode, when connected in a circuit, can only conduct current in one direction.

When an alternating current, such as a sine wave, is applied to a PN junction diode, the diode will only conduct current in one direction, depending on the polarity of the applied voltage. The PN junction diode acts like a one-way valve, and is the basic concept of how rectification happens. In the case of the BYQ28EB-150-E3/81, the rectifier is composed of three PN junction diodes, two of which are connected in series, forming a bridge rectifier. This allows DC to flow in one direction, and prevents AC from flowing in the opposite direction.

In summary, the BYQ28EB-150-E3/81 is a three-phase bridge rectifier with a maximum blocking voltage of 600V and a controllable current capability of up to 150A. It is suitable for harsh environments and can be used for both AC and DC applications. Its working principle relies on the concept of PN junction diode rectification. This allows DC to flow in one direction and prevents AC from flowing in the opposite direction.
